Optimal (v, 4, 2, 1) optical orthogonal codes (OOC) with v <= 75 and v = 71 are classified up to equivalence. One (v, 4, 2, 1) OOC is presented for all v 181, for which an opt...
This paper presents a brief review of current game usability models. This leads to the conception of a high-level game development-centered usability model that integrates current...
Identification of time-varying linear systems, which introduce both time-shifts (delays) and frequencyshifts (Doppler-shifts) to the input signal, is one of the central tasks in m...
We show that for every connected graph G of diameter 3, the graph G3 has average degree 7 4 (G). We also provide an example showing that this bound is best possible. This resolv...
Abstract. We propose an authentication scheme where forgery (a.k.a. impersonation) seems infeasible without finding the prover's long-term private key. The latter is equivalen...
